Beurer OT-80 Personal Fertility Set

The Beurer OT-80, marketed as “Pearl by Beurer,” is a personal fertility set designed for women who want to track their cycle, identify their fertile window, and support natural family planning from home. Unlike standard ovulation tests that measure only one hormone, the OT-80 measures both of the most important fertility hormones — follicle stimulating hormone (FSH) and luteinising hormone (LH) — independently of each other, building a personalised hormone profile over the full cycle to provide more accurate and earlier fertility predictions.

Testing is performed daily using first morning urine and the included paper test strips. Once the strip has reacted, a coloured line confirms the test is complete. The strip is then photographed using the smartphone camera within the free “pearl Fertility” app (iOS and Android), which uses Colorimetrix full-colour spectrum analysis technology to read the hormone levels from the test and control lines — significantly more precise than visual interpretation alone. On the basis of the accumulated hormone data, the app calculates the individual fertile window, predicts ovulation up to 6 days in advance via early FSH trend detection, and identifies up to 8 fertile days per cycle. The app also provides a personalised daily testing schedule, real-time cycle phase information, and a clear graphical hormone profile.

Each OT-80 kit contains 15 FSH test strips, 15 LH test strips, 2 pregnancy tests, and a reusable strip holder. The kit is designed to cover one complete cycle of 21–35 days. CE certified as a medical device. Test strip accuracy: 99% for detecting FSH and LH hormones. Backed by a 3-year Beurer guarantee.

Why Choose Beurer Personal Fertility Set

• Dual Hormone Testing (FSH + LH): Measures both follicle stimulating hormone and luteinising hormone independently — providing a more complete picture of the cycle than single-hormone LH-only tests.
• 99% Test Strip Accuracy: Independent clinical accuracy of 99% for detecting FSH and LH hormone levels using the included test strips.
• Predicts Ovulation Up to 6 Days in Advance: Early FSH trend detection allows the app to flag upcoming ovulation up to 6 days before it occurs — significantly earlier than tests that only detect the LH surge.
• Up to 8 Fertile Days Identified per Cycle: The extended prediction window means more identified fertile days, giving couples more opportunities to conceive each cycle.
• App-Based Colour Spectrum Analysis: The “pearl Fertility” app uses Colorimetrix smartphone camera technology to analyse test strips with full-colour spectrum precision — more accurate than reading strip lines with the naked eye.
• Personalised Hormone Profile: The app builds an individual hormone profile specific to your cycle over time, improving prediction accuracy from one cycle to the next.
• Daily Testing Schedule in the App: The app tells you which hormone to test each day — no guesswork about when or what to test.
• Includes 2 Pregnancy Tests: Confirm pregnancy directly within the same kit once the fertile window is identified.
• Reusable Strip Holder: Included for convenient, hygienic handling during daily testing.
• CE Certified Medical Device.
• 3-Year Beurer Guarantee.

How the OT-80 Works

The OT-80 system works by tracking two key hormones that rise and fall in a predictable pattern around ovulation:

FSH (Follicle Stimulating Hormone) rises in the early phase of the cycle to stimulate egg maturation. An early rise and pattern in FSH levels signals that the body is preparing for ovulation — allowing the app to predict the fertile window up to 6 days in advance, earlier than LH-only tests.

LH (Luteinising Hormone) surges sharply just before ovulation triggers egg release. This surge confirms the approach of ovulation and identifies the peak fertility day.

By measuring both hormones daily and using the app’s colour spectrum analysis to interpret each test strip, the OT-80 creates a complete, personalised hormone profile that accurately maps the individual cycle — including irregular cycles within the 21–35 day range.

Usage Instructions

1. Download the free “pearl Fertility” app (iOS or Android) and create an account. Set up your cycle information in the app.
2. On the first day of your next period, tap the flower icon in the app to mark day 1 of your cycle. The app will then generate a daily personalised testing schedule showing which hormone to test each day.
3. Each morning, using first morning urine, dip the appropriate test strip (FSH or LH as indicated by the app) into the sample for the time specified in the instruction manual.
4. Lay the strip flat and wait for the coloured line to appear, indicating the test is complete (typically a few minutes).
5. Open the pearl Fertility app and photograph the test strip using your smartphone camera. The app analyses the strip using colour spectrum technology and records the hormone value.
6. The app updates your hormone profile and provides current fertility window information, cycle phase status, and ovulation prediction.
7. If pregnancy is suspected after the fertile window, use one of the included pregnancy tests and photograph the result in the app.

Warnings and Precautions

• This kit is designed for cycles of 21–35 days. Women with cycles outside this range should consult a healthcare professional before using the kit, and may require an additional kit for longer cycles.
• Always use first morning urine for testing. Diluted or non-morning urine can affect hormone concentration and result accuracy.
• Conditions that affect the natural hormone balance — including PCOS, thyroid disorders, perimenopause, recent pregnancy, or breastfeeding — can interfere with FSH and LH levels and affect result accuracy. Consult your doctor before use if any of these apply.
• This kit is intended to support natural family planning and cycle awareness. It is not a contraceptive method and should not be used to prevent pregnancy.
• A positive LH test confirms the LH surge but does not guarantee ovulation in all cases. Consult a healthcare professional if you have concerns about ovulation or fertility.
• Test strips are for single use only. Do not reuse.
• Check the expiry date on test strips before use. Do not use expired strips.
• Store test strips in a cool, dry place away from direct sunlight.
• Keep out of reach of children.
